What is a mild symptom during the febrile phase of dengue?

During the febrile phase of dengue, mild symptoms can manifest, and one of those is petechiae. Petechiae are small, pinpoint red or purple spots on the skin caused by bleeding underneath the skin. This symptom is often observed in dengue cases and indicates the impact of the virus on blood platelets and blood vessels.

In the context of dengue, petechiae may appear due to the increased permeability of blood vessels, which the dengue virus can cause. This can lead to a range of other symptoms as well, but the presence of petechiae specifically is notable for its association with dengue fever and its severity can often indicate the potential progression to more severe forms of the disease, such as dengue hemorrhagic fever.

While rash, abdominal pain, and nausea can also occur during the febrile phase, they tend to be either more general or indicative of other issues rather than being as specifically characteristic of dengue as petechiae.
